## Summary
This PR intends to fix the build of WebAssembly applications for the
**ESP32-S3**, which currently fails due to the following error:

```
The proposed fix is to remove an unused include of `userspace.h` from
`kmalloc.h`, which ends up including the arch-specific `nuttx/irq.h` that
contains inline assembly instructions.
## Impact
No functional changes, should have no impact.
## Testing
Custom defconfig based on `esp32s3-devkit:nsh` for enabling WAMR support.
CI build pass.
